[R] Need help for a statistical problem

[james brown]

Hello Dear
I need to select among 700 objects  a good
representative sample. These
objects
could be residential houses, commercial buildings,
trucks, etc.
How to get a good sample size and select a set of
objects that is very
representative.

The second part of my question is to find a
statistical model in R that
detects objects that are most
likely used as their owners told the municipality. For
example, if a
restaurant is suppose
to have 5 tables, we want to know that it doesn't have
more. The goal
is to have a model that
flags such restaurant for inspection.

Cheers, Dan
